GAR is a spelling mistake stemming from someone saying he's gay for a character. In other words, it's a man enthralled by a MALE character. So yeah, women can't be "gar" in the true sense. They can be badasses for all I care, but saying they're "gar" is illogical. You might as well say they're saxophones.
And why are you talking about my penis all of a sudden? Holy dog shit, you ARE queer. So why not admit it right away instead of trying to paint Kaiji as "moe" when he's not? Freaking cocksuckers.
